Touch screen won't work

My DexArm won’t work with a touch screen.
The touch screen is connected to DexArm with USB typeC-typeC.
The screen shows GUI correctly but no reaction on the DexArm.

When connected to PC and operating from Rotrics Studio (V1.0.2),
the DexArm work perfectly.

Only operation from a touch screen is ignored by the DexArm.
Any help? Thank you in advance.
(By the way, my touch screen don’t show wifi icon, no setting. It’s correct?)
